How can we directly download a report from the export link to a specific local folder on the users system without showing the dialog box to save or open.
Users do not want to select every time where to save the file.

Basically there is a shared drive mapped in their windows explorer and they want all the reports to be downloaded/exported directly in to that folder on clicking a button or link.
For some of the reports they don't even want to see the report and it should be just a download button and they click and it should save it on their shared drive.

I know that it is a browser option where we can setup default folder, but if we do that every thing that is downloaded from the browser will go into that folder and that is not suggestible because that shared drive consists of only project specific reports.

This is some thing crucial for the users now.Any ideas please help ?

Your help is highly appreciated. Thanks for your time.
